MRI appearances of an ectopic pituitary adenoma : case report and review of the literature

MR images of an ectopic pituitary adenoma have been published in only a single case, a suprasellar mass. We present a patient with Cushing's disease in whom MRI revealed a pituitary adenoma within the sphenoid sinus. Radiologic characteristics of ectopic pituitary adenomas are reviewed, with em...

Zusammenfassung:	MR images of an ectopic pituitary adenoma have been published in only a single case, a suprasellar mass. We present a patient with Cushing's disease in whom MRI revealed a pituitary adenoma within the sphenoid sinus. Radiologic characteristics of ectopic pituitary adenomas are reviewed, with emphasis on MRI, which demonstrates a soft tissue mass, isointense with gray matter on T1-weighted images, which enhances in a heterogeneous manner.
